Of the commonly circulated coins in the United States, the Half Dollar is the thickest, measuring 2.15 mm (0.085 inches).
For context, here’s a comparison of the thicknesses of other common US coins:
- Nickel: 1.95 mm (0.077 in)
- Quarter: 1.75 mm (0.069 in)
- Penny: 1.52 mm (0.060 in)
- Dime: 1.35 mm (0.053 in)
It’s interesting to note that despite being smaller in diameter than the Quarter, the Nickel is thicker. Historically, the Nickel was thickened to address concerns about it being easily lost.
